I have installed a bunch of C64 related gamebases and such.
Here is one of them.

2nd on my PC is C64 Forever, and I have the Plus Edition!

3rd on my PC is Amiga Forever, again I have the Plus Edition.
Of Course I should have the GAMEBASE!
I have Amiga 2.3, and both Version 16 and 17 of the C64!
As far as Emulators go, I have Vice 2.4 and 3.5, HOXS64 1.1.0.2 to 1.1.0.5, CCS64 V3.9.2, and Denise 1.1.
And Not a lot of players would have Z64K, a Java Script based Emulator, which also emulates Atari 2600 and ZX Spectrum.
I have not tested the other Emulators on this one however, and so far the emulator for C64 itself is not performing up to the standards.
I use YAPE 1.2.0 to run my Plus 4/C 16 programs.
It works better than the one came with the VICE package.
For VIC 20 programs I continue to use the one inside the VICE package.
I use FS-UAS and WinUAE for my Amiga Programs, and ZXSpin and FUSE to run my ZX Spectrum Programs.
WinUAE is better, and FUSE is better.
As far as Extra Stuffs for the C64, I have SidPlay V 2.6, DirMaster V 3.1.5, C64 Studio V 1.0, Quick 64! (from Gamebase 64).
and HVSC 75.
